NRRD reader should support time
There is no way right now to read a time sequence through a set of NRRD files. There are two ways in which it makes sense to represent a time series with NRRD files:
- As a simple sequence of files
- As an internal "spatial dimension" in the metadata
Either one should be valid, but the first one is probably both easier to implement and easier for most users to produce. It would probably be sufficient (at least in the short term) to just implement the first one.
